摘要: Abstract We have synthesized two sensitizers based on the 3-methyl-1,1-cyclohexane, a novel σ-linkage to prepare dianchored dyes. These dyes are difunctionalized systems with aniline-donor (D), π-conjugated spacer (π) thiophene or bithiophene and cyanoacetic acid as acceptor anchoring group (A). The UV–vis absorption Differential Pulse Voltammetry been used study effect of both π-spacer. relevant increase molar extinction coefficient these has investigated by theoretical calculations. dye bearing results in broader higher well an adequate efficiency transfer charge from D A respect photovoltaic properties without co-adsorbent studied. derivatives present photocurrent density which better performance single derivative given rise value 7.8% is stable up 1000 h after device assembly.
